CHARLEQ E. HARP, OF LOS ANGELES, CALIFORNIA. BOND FOR HOLLOW-WALLCONSTRUCTION.

Specification of Letters l'atent.

Patented Feb. 24, 1914.

Application filed August 2, 1912. Serial No. 712,881.

To all whom it may concern: Be it known that I, CHARLES B. HARP, acltlzen of the United States, and resident of Los Angeles, in the countyof Los Angeles and State of California, have invented certain new anduseful Improvements in Bonds for Hollow-Wall Construction, of which thefollowing is a specification.

My invention pertains to building construction, and it has specialreference to a metal bond adapted for use in connection with buildingblocks, slabs, tile or other elements of like character, which isdesigned to hold the elements together during the process of laying upwalls.

It comprises a sheet metal plate of suitable size and shape, which hasstruck out and bent therefrom certain wings, which are so disposed thatin applying the bond, to the elements the latter will be held inalinement with each other and spaced apart so as to form a hollow wall,all of which will now be set forth in detail.

In the accompanying drawings, Figure 1 is a perspective View of myimproved metal bond. Fig. 2 is a top view of the bond as applied to awall. Fig. 3 is a vertical cross section of portion of a wall with thebond in a locking position.

I construct the bond in the following manner: It comprises a sheet metalplate, 4, rectangular in shape, at each end of which is a down turnedwing 5 extending across the plate, and a tongue 6 is struck out of thebody of the plate which extends upwardly, at each end, so that it is onthe same plane as the cross wing 5 below the plate. A space 13 is formedin the plate by striking up each tongue 6. Intermediate the ends Istrike out and bend upwardly four wings 7, at the margins of the plate,and four similar down-turned wings 8 interiorly, each set of wings beingon the same plane, and the intermediate wings are so located, as toposition that the distance between the end wings, 5-5, and the interiorwings 88, and between the tongues 66, and marginal wings 7-7, are thesame as the thickness of the tile, slab, or other building elements usedin the construction of the wall. The distances between the marginalwings 77 in this case would represent the width of the air space formedbetween the budding elements 9, which elements may be of any suitablematerial. As shown in Fig. 2, the bond thus constructed, is laidtransversely across the abutting ends of two companlon walls 10, 11,thereby providing an open space 12 between them, as the interiordown-turned wings 8 space apart and hold the lower slabs, while theup-turned marginal wings 7, 7 space apart and hold the superposed slabs.The downwardly-projectmg transverse-wings 5 in like manner lap over theoutside of the joint of the two abutting slabs, and the upwardly-projecting tongues 6 over-lap the joints of the superposed tile,This bond is adapted to form corners wlthout any changes in structure,and may be used in a variety of ways with little if any modification.The bond, constructed in this manner permits me to lay up a wall withover-lapping joints, so that the slabs do not have continuous verticaloints in the different superposed layers, as it is not necessary tolocate the bond at a joint, but it may be placed at any point along thevwall, as well as at the joints. The space 13 permits the cement to passthrough which looks the bond in position. This opening also permits thecement to pass to the joint between the abutting ends of slabs which lieimmediately below the space 13, as shown in Fig. 2.

What I claim as new, is

A metal bond comprising a plate having at each end wings projecting inopposite directions from the plate, the plane of said wings being atright angles to the plane of the plate, said plate having at anintermediate point four wings projecting transversely from one face, andfour wings projecting transversely from the other face, thereby forminga narrow neck, four of said intermediate wings which project from oneface of the plate being located to form spaces between their outer edgesand the outer edges of the plate to enable the plate to overlap the endof a stud with the outer edges of the latter wings bearing against thestud, the four intermediate wings which project from the other face ofthe plate being located with spaces between them and the neck, two ofsaid intermediate wings on one side of the plete heing in the same planeday of May 1912, in the presence of witwith two of the mtermedlate wlngson the nesses.

other side of the plate and the other two I sets of correspondingintermediate wings be- CHARLIE A ing in the same plane with each other.Witnesses:
